Wireless door intercom apparatus and system comprising same

Abstract

A wireless door intercom system comprises a wireless door intercom apparatus affixed to the entrance of a building and a portable wireless signal transceiver. The wireless door intercom apparatus comprises an audio transmission module for receiving sound and converting same into a first audio signal and a wireless signal transceiver module for converting an image signal and the first audio signal into a transmission signal which is in turn transmitted to the portable wireless signal transceiver. An audio transceiver of the portable wireless signal transceiver is adapted to receive a second audio signal input which is in turn transmitted to the audio transmission module. The wireless door intercom apparatus is also adapted to receive a lock open signal generated by a keypad of the portable wireless signal transceiver so as to remotely enable a lock controller of the wireless door intercom apparatus to open a lock connected to the wireless door intercom apparatus.
